Bleaching earths are generally composed of up to three types of clay minerals: bentonite, attapulgite and sepiolite. The minerals act as absorbers with capacity being dependent on mineralogical structure and properties, such as surface area, particle size distribution, porosity and surface activity.

Bentonites are a soft stone with the capacity to absorb substances dissolved in water and other liquids. The minerals have been formed over time due to the natural adaptation of volcanic ash. Bleaching earths are found in mines around the world, including North America, South America, Europe, the Middle East and Asia.

It is widely used in the refining, decolorizing and bleaching of edible oil & fats. Major demand has been experienced from Asian countries such as Indonesia, Malaysia, China, and India. Favorable government regulations and policies in these countries have had a positive influence on the market growth.

The growing acreage yield of oil seed crop and technological developments in the production process have remained key driving forces for the vegetable oil & fat industry. Growing demand for biofuel which is derived from vegetable oil is also one of the factors influencing the demand of activated bleaching earth in this industry, particularly in the developed countries.

Bleaching earth is usually made up of montemonillonite and bentonite clay, which are rich in aluminum and silicon content. They also contain magnesium, calcium, and iron. Bleaching earth is of two types: natural bleaching earth and acid activated bleaching earth. It can be categorized depending on the process employed to produce it. Natural bleaching earth is a clay that is mined, crushed, dried, ground, and sized. On the other hand, acid activated bleaching earth is produced using steps such as mining, crushing, acid treatment, washing, filtering, drying, grinding, and sizing. Bleaching earth is utilized in a number of industrial applications in the refining of vegetable, animal, mineral oil, etc. Asia Pacific is a major region of the bleaching earth market, with high demand for the product from major vegetable producers such as Indonesia, Malaysia, Thailand, Philippines, China, India, etc.

Bleaching earths, used as part of the process that removes impurities from edible oils prior to final application, are a fast growing market that is estimated to be worth US$3.59bn by 2022.

Demand for activated bleaching earth is projected to arise from Malaysia, Indonesia, China, and India on account of increasing production of vegetable oil in these countries. The growing responsiveness to biofuel which is derived from vegetable oil is also expected to have a positive influence on the market growth. Large amount of oil absorption during the refining of mineral or edible oil is expected to remain a key challenge for market participants.

The Global Activated Bleaching Earth Market is categorized on the basis of application. On the basis of application, the market is further segmented into edible oils, mineral oils, and others. Among these, edible oils segment holds the major share of the market due to the growing use of bleaching agents for the purification of vegetable oils and fats in the food industry. The increasing demand for bleaching earth in the heavy end industries such as oil & gas, petrochemicals, food & beverages has propelled the automotive segment to witness a higher growth in the market. In addition to, it is predicted that the mineral oils & lubricants segment is set to grow at a moderate rate in the market during the forecast period.

The Global Activated Bleaching Earth Market is spanned across five key regions of the world namely Asia Pacific, North America, Europe, Latin America, and the Middle East & Africa. Among these, Asia Pacific holds a major share of the global market and is expected to continue its dominance due to rising demand for bleaching earth in oil & gas, petrochemical industries, and others. These agents are widely used to improve the optimal performance and standard of oil in heavy end industries. Due to these factors, China, India, Indonesia and Malaysia are the major players in this region. The North American region is predicted to witness a higher CAGR in countries such as U.S.A., Canada and Mexico owing to growing demand for biocompatible materials in the automotive, construction and industrial machinery.

In terms of application, the bleaching earth market can be categorized into oil refining, decolorization, purification, and other applications. Currently, the market is dominated by the oil refining application segment, which is anticipated to continue its dominance during the forecast period. The segment is anticipated to expand at a rapid pace during the forecast period, due to the increasing demand for oil processing applications with increase in oil production, especially in Southeast Asian countries such as Indonesia, Malaysia, Thailand, Philippines, etc.
